OVERVIEW

The LCD meter provides local indication of the output, and abbreviated diagnostic messages governing transmitter operation. The meter is located on the electronics board side of the transmitter, and receives its output information directly from the electronics board microprocessor. An extended cover is required to accommodate the meter.

The meter features a two-line display that accommodates five digits for reporting the process variable on the top line, and six characters for displaying engineering units on the bottom line. And in addition to units of pressure, the new LCD meter is capable of displaying flow and level units. The meter uses both lines to display diagnostic messages. You can configure the meter to display the following information:

� Engineering Units� Percent of Range� User-Configurable LCD Scale � Alternating between any two of the above

The user-configurable scale is a new feature that enables you to configure the LCD meter to a custom scale for flow or level. You can configure the meter using a Model 275 HART Communicator or AMS. With the user configurable scale feature, you can define the decimal point position, the upper range value, the lower range value, the engineering units, and the transfer function.

The user-configurable meter scale transfer function is independent of the transmitter analog output transfer function, which allows the meter to display square root flow output while the analog output remains linear with the pressure input.

SAFETY MESSAGES

Procedures and instructions in this manual may require special precautions to ensure the safety of the personnel performing the operations. Information that raises potential safety issues is indicated by a warning symbol ( ). Refer to the following safety messages before performing an operation preceded by this symbol.

Explosions can result in death or serious injury.• Do not remove the transmitter covers in explosive

atmospheres when the circuit is alive.

• Both transmitter covers must be fully engaged to meet explosionproof requirements.

• Before connecting a communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or nonincendive field wiring practices.

6

INSTALLATION PROCEDURES

The installation procedures vary depending on the style of housing and the meter kit. Examine your meter part numbers closely to ensure that you perform the appropriate procedure.

Part Numbers 03031-0193-0101and 03031-0193-0111

The meter kit includes:� one LCD meter display� one extended cover with O-ring� two captive screws� one ten-pin interconnection header

Use the following procedure and Figure 3 to install the LCD meter.

NOTEThe LCD meter and the electronics board areelectrostatically sensitive; observe handling precautions for static-sensitive components.

FIGURE 3. Exploded View of the Transmitter and LCD Meter.

1. If the transmitter is installed in a loop, secure the loop and disconnect power.

2. Rotate the electronics housing up to 180 degrees (left or right) to improve field access to the two compartments or to better view the LCD meter. To rotate the housing, release the housing rotation set screw and turn the housing not more than 180 degrees from the orientation shown in Figure 1 on page 2. To rotate the housing greater than 180 degrees, refer to the Model 3051 product manual, publication number 00809-0100-4001.

NOTEDo not rotate the housing greater than 180 degrees without first referring to the Model 3051 product manual. Rotating the housing greater than 180 degrees will damage the sensor module and void the Rosemount warranty.

3. Remove the transmitter cover opposite the field terminal side. Do not remove the instrument covers in explosive environments when the circuit is alive.

4. Remove the alarm and security jumpers from the electronics board, and insert them in their new positions above and below the meter readout on the meter assembly.

NOTEPlace the security jumper in the OFF position to enable meter configuration changes.

5. Insert the interconnection header in the ten-pin socket exposed by removal of the jumpers.

6. Remove and discard the two captive screws from the electronics board. To do so, loosen the screws to release the module, and pull out the screws until they are stopped by the captive thread inside of the circuit board standoffs. Then continue to loosen the screws until you are able to remove them.

7. Gently pull the electronics board out of the housing. Do not detach the ribbon cable from the back of the electronics board.

8. Decide which direction to orient the meter, and position one of the four connectors on the back of the meter assembly to accept the interconnection header.

9

9. Attach the meter to the electronics board, taking care to properly engage the ten-pin interconnection header.

10. Slide the electronics board and meter assembly intothe transmitter housing, taking care to properly engage the posts from the housing with the receptacles on the electronics board.

11. Insert the two mounting screws supplied with the meter into the two holes on the meter assembly. Tighten the screws to secure the meter and electronics board to the transmitter housing.

12. Attach and tighten the extended cover. Transmitter covers must be fully engaged to meet explosion proof requirements and to achieve a proper environmental seal.

13. Refer to “Custom meter Output” on page 23 to configure the meter.

Note the following LCD temperature limits:Operating: –4 to 175 °F (–20 to 80 °C)Storage: –40 to 185 °F (–40 to 85 °C)

NOTEElectronics board revision 5.3 or later (all shrouded designs) have increased functionality that allows verification testing of alarm current levels. If you repair or replace the transmitter electronics board, sensor module or LCD meter, it is recommended that you verify the transmitter alarm level before you return the transmitter to service (see “Alarm Level Verification” in the Model 3051 product manual, publication number 00809-0100-4001).
